There was a problem hiding this comment.
Bill has some good recommendations here for patching code. https://github.com/lyft/lyft-hadoop#patching.
Do we want to push it to a separate function at least and maybe behind a flag too.

…subquery code
### What changes were proposed in this pull request?
This PR fixes an issue that `EXPLAIN CODEGEN` and `BenchmarkQueryTest` don't show the corresponding code for subqueries.
The following example is about `EXPLAIN CODEGEN`.
```

df.createTempView("df")
spark.sql("SELECT (SELECT min(id) AS v FROM df)").explain("CODEGEN")
scala> spark.sql("SELECT (SELECT min(id) AS v FROM df)").explain("CODEGEN")

### Why are the changes needed?
For better debuggability.
### Does this PR introduce _any_ user-facing change?
Yes. After this change, users can see subquery code by `EXPLAIN CODEGEN`.
### How was this patch tested?
New test.
Closes apache#30859 from sarutak/explain-codegen-subqueries.

…ries if AQE is enabled
### What changes were proposed in this pull request?
This PR fixes an issue that when AQE is enabled, EXPLAIN FORMATTED doesn't show the plan for subqueries.
```scala
val df = spark.range(1, 100)
df.createTempView("df")
spark.sql("SELECT (SELECT min(id) AS v FROM df)").explain("FORMATTED")
== Physical Plan ==
AdaptiveSparkPlan (3)

```
After this change, the plan for the subquerie is shown.
